Another option would be to put the brake light switch right on the brake pedal, and leave your brake line hydraulics alone. Most OEM's today use pedal switch and they're easy to find. Take a look at your "Other" car, and see how it's connected.

Admittedly, the balance bar is preferred with all aftermarket brake system, two master cylinders, etc. But with a single master cylinder made for 4 wheel disk brakes, Corvette, Ford T-Bird, Lincoln, Cad; use a proportioning valve in the rear brake circuit to balance the front/rear brake effort. You dial this in when you put the car on the street.

That being said, I have 11" rotors/4 piston calipers in front, 10" rotors/single piston calipers in rear. Master cyl is T-Bird. Weight distribution and tire size on this specific car, my dial in was all the way open. So I didn't need one. Had I used a different engine, different tires, it may have worked out differently.
